* Mr. Couch speaks of the effects of a wound from another species of Trachinus (T. Draco) in 

 the following terms, " I have known such effects to arise from the puncture of the spine on the 

 gill-covers of this fish, as can only be accounted for on the supposition of its conveying some 

 venomous quality. In three men who were wounded by one fish, the pain and tension proceeded 

 from the hand to the shoulder in a few minutes." Linn. Trans, xiv. p. 71.
